Does anyone know how long the GB4000 M.O.P.A. plasma ray tube last? I am thinking that after a few years the gases in the plasma ray tube would eventually dissipate just like a plasma screen television.

I guess the question is how long does the plasma ray tube last as well as how much it would cost to replace. BTW, is there anyway a person like myself can manually replace the gases or is that too dangerous. Thanks.
